"The last three (1000-1002) are shown as if they are rules with these Order values because they seem to behave that way. I don't know if that's how they are really implemented. This is important to know because if you have a filter that moves a message to a folder, it will stop the filter processing for that message and it will never get to the GMS Phone Notification, the Forward To Email/GMSPhone or the Move To Inbox."

If you want to forward these messages to another email address you will have to add your own filter to forward messages that comes ahead of your filters that move messages to folders.
